Fourier and Laplace transformations

[karthik3k]

Im sorry. Im really new to this. Whats the Difference between FT and LT ?

The FT is two sided (integral from -infinity to +infinity) and uses a purely imaginary transform variable.

The LT is usually single sided (integral from zero to +infinity) and uses a complex variable that is not restricted to pure imaginary.
